Description
The GRACO 551364 is a 3/4″ stainless steel lock washer designed to secure fasteners and prevent loosening due to vibration or torque in GRACO equipment. It is typically made from corrosion-resistant stainless steel and is used in assemblies where reliable, long-term fastening is required.
Key Features:
- Lock Washer
- 3/4″
- Stainless Steel (likely 18-8 or 304 grade, based on industry standards for similar parts)
- Compatible with 3/4″ bolts and nuts; suitable for use in GRACO equipment assemblies
- Split design for spring action and vibration resistance
- Corrosion-resistant material for harsh environments
- Reliable performance in high-vibration and torque applications
Applications:
Used in machinery assembly, industrial equipment, and any application within GRACO systems requiring secure fastening and resistance to vibration loosening.
Installation Notes:
- Using genuine GRACO parts ensures proper fit, function, and longevity of equipment, reducing the risk of fastener failure and equipment downtime.
- Install beneath the nut or bolt head with the split ends slightly offset
- Tighten the fastener to compress the washer, which helps prevent loosening
- Use with a flat washer when fastening softer materials or oversized holes for added support
- Regularly inspect lock washers for signs of wear, corrosion, or deformation
- Replace washers if they lose their spring action or show visible damage
- Ensure proper torque is applied during installation to maintain effectiveness
